Officials made the announcement on social media at 4:15 p.m.

According to the city's traffic cameras, the closure is due to a multi-vehicle incident that blocked two lanes on the highway.

Traffic is being detoured past the incident, but police are requesting other drivers avoid the area if at all possible.
